Is buying things from Ebay really the way to go

..the way to go where? You forgot to finish your question!!!!!

sure, l was skeptical about it, but its really good and reliable, you get many things from factory thus skipping the extra costs that stores tack on (walmart,bestbuy,etc)

just make sure you only buy from sellers with 95% positive rating

Just look at Ebay is revenues. That should tell you they are doing pretty well. To the tune of Billions each year!
There is actually a company launching an auction site this weekend called Dubli. They are from Europe and will be bigger than Ebay, Amazon, and Google, as they are proving in Europe. There is a business opportunity as well to make money without having to sell things to people.
